An Important Demonstration in Lab Safety
- Can be prepped and performed in about 15 minutes
- Recommended for grades 5-12
When flammable liquids burn what is actually burning- the liquid or the vapors above the liquid? It is the vapor that mixes with the oxygen that is burning. The vapors from the flammable liquids can also travel a long distance before reaching the ignition source. This safety demonstration should teach students why no ignition sources must be present when flammable liquids are being used.
